100 * The 21040 has a stupid restriction in that the receive
101 * buffers must be longword aligned.  But since Ethernet
102 * headers are not a multiple of longwords in size this forces
103 * the data to non-longword aligned.  Since IP requires the
104 * data to be longword aligned, we need to copy it after it has
105 * been DMA'ed in our memory.
106 *
107 * Since we have to copy it anyways, we might as well as allocate
108 * dedicated receive space for the input.  This allows to use a
109 * small receive buffer size and more ring entries to be able to
110 * better keep with a flood of tiny Ethernet packets.
111 *
112 * The receive space MUST ALWAYS be a multiple of the page size.
113 * And the number of receive descriptors multiplied by the size
114 * of the receive buffers must equal the recevive space.  This
115 * is so that we can manipulate the page tables so that even if a
116 * packet wraps around the end of the receive space, we can
117 * treat it as virtually contiguous.
118 *
119 * The above used to be true (the stupid restriction is still true)
120 * but we gone to directly DMA'ing into MBUFs (unless it's on an
121 * architecture which can't handle unaligned accesses) because with
122 * 100Mb/s cards the copying is just too much of a hit.
